1,问题:如下所示:
import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.test.context.junit4.SpringRunner; public class MoveSysUserTest { @Autowired private MoveSysUser moveSysUser; @Test public void testMoveSysUser() { boolean res = moveSysUser.moveSysUser(); System.out.println(res); } }
此时运行,会提示moveSysUser为空,报空指针异常
2,解决方法
1)添加注解:
@RunWith(SpringRunner.class) @SpringBootTest
import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.test.context.junit4.SpringRunner; @RunWith(SpringRunner.class) @SpringBootTest public class MoveSysUserTest { @Autowired private MoveSysUser moveSysUser; @Test public void testMoveSysUser() { boolean res = moveSysUser.moveSysUser(); System.out.println(res); } }2)继承一个添加了以上注解的类
